T0 (LUy 11.171.0711, '1'21 77M!{femm/27170:

Beit. known that I. Enwiiiii) H. vimini-LN, a ,citizen ot thi3 United States, residing` at Rentiesville, in District 1l), Indian l`erri'torv,

have invented a new and useful Combined 'Car and Air-Brake Coupling, of which the following is aspecification.

This invention relates to combined cai` andair-bralte couplings, and has for its object to provide means whereby the couplin'o` of the draw-heads will automaticallv ellect the uiiio'n of the train-pipe Couplings of adjacent cars.

A further object of the invention is to provide a coupler havingy a laterallv-movable jaw provided with gnidingeiiang A.. wherebv when the cars are coupled the ilangeswill interengage and Vtorce the jaws to closed or opera-tive position.

A further object is to provide the coupler with a locking member adapted 'to aute- 'nia-tioally engage the shank oi the movable jaw for locking the same iii engagement with the mating jaw of' an adjacent cmiplci when the union of said couple is eliected.

A further object is to provide improved meansr for automatically opening and closing the valve or stop-cock of the train-pipe as the cars are coupled and uiicoupled.

r A still further object of the invention is to generally improve this class to increase their utility, dur: bilitv, and elliciency, as well as to reduce the cost ol manufacture.

With these and other objects in view the invention consists in the construction and novel combination and arrangement olt paris hereinafter iullv described. and illustrated in t-he accompanying drawings, it britte` understood that various changes in form. proportions, and minor details of' construction may be resorted to within the scope ol'A the appended claims.

In the accompanying drawings, forming' a part oiV this specification, :Figure 1 a top plan view oi a combined car and air-brake coupler constructed in accordance with mv invention, showing the pivoted jaws in operlf`ic. .2 is a similar view showative position. I

Fig'. is a ing the draw-heads uncloupled.

Fig. i is a vero'l devices so as tical sectional lview taken on the line 1 L1 of Fig. l. 5 is an end view ot one ofthe d `:iw-heads. Fig. 6 is a perspectivefview of the locking` member dei ached.

Similar numerals ol' reference indicate cor responding parts in all ol' the 'figures of the drawings.

The improved Coupler comprises a drawhead preferably rectangular iii shape and provided on one side thereof with a longitudinal slot orrecess G, as shown. Pivoiallv mounted on the di.a\\'-head as indicated at 7, is a movable jaw S, provided with a reduced shank 9,' the free end ol' which is sea-ted within the openingl o and inclined or beveled, as indicated at 10, vfor the purpose here.- ina-'liter referred to.

The free end of the pivoted jaw is provided with a. shoulder 11, deiiiiing a lateral projection 12, havingT a seiiiicircular opening 13 iformed therein and adapted to register with a. corresponding opening formed in the free end oi" the movable jaw of the adjacent draw head when said draw-heads are coupled. The pivoted jaw 12 oi" each d.awliead` is provided with oppositely-disposed guide-flanges 1*-1, the active faces ol'A which are inclined or beveled, as indicated at 15, for engagement with the Correspondinglv-inclined faces oi" similar guide-flanges 16, secured to or formed integral with the drawlieads, as shown, so that when the draw-heads are coupled the guido ilanges will interengagc, and thus force the pivoted ja 's to closed or opera-tive position.

Communicatingwith the longitudinal recess 6 of each coupler is a vertical recess 17, in which is mounted for sliding movement a. wedge-shaped locking memberlb, adapted to enegaee the inclined face ol' the shank 9 when the jaws are in closed. position and lock the same against lateral movement. The locking members' 1S uormallv rest on the reduced sbanlis 9 of the pivoted jaws S, so that when the tree ends of'the jaws are forced iiiwardliY bv engagement with the guiding'- 'llanji'es said` lockingr members will drop by gravity to operative position` between the inclined laces of the shanlts i) and. the adjacent walls of the shank. As a means 'for elevating' the locking members to permit un coupling:r -ol the cars there is provided a suit.- able crank-shaft 19, one end of which is connec-ted to the loc-king member through the. medium of a chain 20, while the opposite end thereotl extends laterally beyond the side of the car and is provided with a suitable operating-handle, by means oiI which the shaft may be rotated to elevate the locking member. and thus release the pivoted jaw. I

The draw-headsv 5 are each provided with a longitudinal opening 2i, in which is seated a fluid-pressure pipe 22, nected through the medium of a branch pipe 23 with a train-pipe 2st. The tluid-presstue pipe 22 is mounted for longitudinal movement in the slot 2l and the branch -pipe 23 extends through an opening 25, communicatJ ing with the slot 2l, thereby to permit a corresponding longitudinal movement of the branch pipe when the cars are coupled. The inner end of the pipe 22 is connected to a cross-bar 26, seated in a transverse opening 2T, formed in the rear end of the draw-head, said bar by enga-gement with the walls of the recess serving to limit the longitudinal movement of the fluid-pressure pipe. The outer orfree end of the pipe 22 is provided with an enlarged head 2S. in vwhich is seated a gasket' 29I adapted to engage the corresponding gasketl on the Huid-pressure pipe of the adjacent draw-head. so as to permit the free passage of air from one pipe to another. Thehead 2Q is formed with an annular shoulder 30, and interposed between said shoulder and a similar shoulder 31. formed in the draw-head 5, av ycoil-spring 32. the normal tendency of which is to exert an outward pressure on the head of the pipe 22. with the branch pipe 23 disposed adjacent the front wall ofthe slot 25.

The passage otl air to the pipe 22 is controlled by a stop cock or valve 33, having secured thereto and mounted for movement therewith a segmental rack Si. the teeth of which mesh with the teeth ol the eccentric 35. The eccentric 35 is pivotally mounted in a stationary hanger 3G. depending from the adjacent draw-head and rigidly secured to ,said hanger and retained in position by the pivot-pin 3T is a yoke 23S. which embraces the rack Si. and serves to normally hold the latter in engagement with the teeth on the eccentric. The eccentric .'35 is preferably weighted, so that the teeth on the eccentric will be held in engagement with the teeth on the lever Si when the latter is in up- Y iiight rposition and assist in elevating the tree nd ot' said lever when the latter isin lowered position and the cars uncoupled. as best shown in Fig. 3 ot' the drawings. lt will thus be seen that as the cars are coupled the pipe 22 will move longitudinally ot the dra\\'head. which causes'the rack 34 to engage and rotate the caln or eccentric 55 to the dottedline position shown in Fig. 3 otl the drawings. thus depressing the lever 't3-l and opening the valve 33. so that the air t'rom the train-pipe 2l vis free to tiow through the Huid-pressure pipe ot'one draw-head to the adjacent draw head.

said pipe being con-v Yhen the cars are uncoupled, the spring 32 will lorce the pipe 22 outwardly, thus causing the teeth'on. the rack to rotate the member 35, which latter-being weighted and eccentrically mounted in the hanger Swvill elevate the -rack to lthe 'full-line posit-ion shown in Fig. 3 ot' thev drawings, thereby closing the valve 'and cutting off communication between the train-pipe and tiuid-pressurepipe 22.

The yoke 3S is preferably disposed at an angle to the` longitudinal plane ot' thc hanger 36 and is so arranged as to permit free move'- vment ot' the rack within the yoke when the lcars are coupled and uncoupled without lia- ,I bility of the teeth on the rack becoming disengaged from the teeth on the eccentric.

From the foregoing'description it is thought that the construction and operation of the device 'will be readily understood by those skilled in the art. and further description thereotl is deemed unnecessary.

Having thus described the invent-ion. what is claimed is- 1. The combination with a dra w-hea d having a huid-passage. a valve controlling said passage and provided with operating means and an eccentric engaging the operating means for moving thevalve to open and closed position as the draw-heads are coupled and uncoupled.

2. The combination with a draw-head having a' lluidpressure pipe mounted for longitudinal movement therein. a valve. and an eccentric adapted to engage the valve and actuated by the movement ol` the Huid-pressure pipe for opening and closing said valve.

4. The combination with a draw-head having a fluid-pressure pipe mounted for longitudinal movement therein. and provided 'with a depending branch pipe. comnnlnicat ing with said duid-pressure pipe. a valve having a rack operatively connected therewith. and a toothed cam engaging -the rack for moving the valve to open and closed posi# tion. l

5. The con'ibination with a draw-head having a fluid-pressure pipe mounted for longitudinal movement therein. a branch pipe provided with a valve. a hanger depending from the dra\\'head. and an eccentric pivotally mounted in the hanger and adapted to eugagc the valve for moving the latter to open` and closed position.

o. The combination with a draw-headhav ing a duid-pressure pipe mounted i'or longi- IOO " 'tudinal movement therein, a branch pipe diepending from the fluid-pressure pipe and pro vided with a valve, a lever operatively connected With the valve, an eccentric engaging the lever for moving the valve to open and closed position, and a-yoke embracing the eccentric and lever, respectively.

7 Thecombination with a. draw-head hava movablejaw pivetally mounted for lateral movement on the dravwhead and provided Witha reduced shank seated in the longitudinal slot, a wedge-sha ed locking member mounted in the Vvertica slotl and adapted to engage the shank of the jaw for locking the same in` closed position, a branch pipe com-- municating With the i'luid-pressure pipe and provided With a valve, a segmental rack operatively connected with the valve, and an eccentric provided with eripheral teeth adapted to engage the teet of ,the rack for moving the valve to open and closed position when the draw-heads are coupled.
